Authors' conclusion

Our finding suggests that some amount of discomfort or pain during exercise may have beneficial analgesic effects; however, this is not likely via activation of the descending pain inhibitory system.

Study context

Population
People with symptomatic knee osteoarthritis (OA) (baseline data from two clinical trials)
Participants
68 people
Exposure
At least a one-unit increase in pain with exercise vs no pain increase
Outcome
EIH: increase in pressure pain threshold (PPT) after a bout of exercises, by pain evoked during exercise (maximum pain rating 0-10)
Methodological detailsbaseline data from two clinical trials, causal mediation analysis
  • Baseline data from two clinical trials

As reported in the abstract

Observational data: associations, not effects.

Further findings

Mediation by conditioned pain modulation (CPM) efficiency of the relation between pain during exercise and exercise-induced hypoalgesia (EIH)

CPM efficiency did not mediate the relationship between pain during exercise and EIH (OR)
